Can You Drink Tap Water in Corpus Christi?

Yes, Corpus Christi's tap water is generally considered safe to drink as Corpus Christi has no active health based violations of the Safe Drinking Water Act (SDWA) that we are aware of. Other factors such as lead piping in a home, or low levels of pollutants on immunocompromised individuals, should also be considered, however. To find more recent info we might have, you can check out our boil water notice page or the city's water provider website.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Corpus Christi's water utility, City of Corpus Christi, had 2 health-based violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. The last violation for Corpus Christi was resolved on Feb. 28, 2021. This assessment is based on the City of Corpus Christi water system, other water systems in the city may have different results.

While tap water that meets the EPA health guidelines generally won’t make you sick to your stomach, it can still contain regulated and unregulated contaminants present in trace amounts that could potentially cause health issues over the long-run. These trace contaminants may also impact immunocompromised and vulnerable individuals.

The EPA is reviewing if it’s current regulations around pollutant levels in tap water are strict enough, and the health dangers posed by unregulated pollutants, like PFAS.

Water Quality Report for Corpus Christi Tap Water

The most recent publicly available numbers for measured contaminant levels in Corpus Christi tap water are in its 2020 Water Quality Report. As you can see, there are levels which the EPA considers to be acceptable, but being below the maximum allowable level doesn’t necessarily mean the water is healthy.

Lead in tap water, for example, is currently allowed at up to 15ppb by the EPA, but it has set the ideal goal for lead at zero. This highlights how meeting EPA standards doesn’t necessarily mean local tap water is healthy.

EPA regulations continue to change as it evaluates the long term impacts of chemicals and updates drinking water acceptable levels. The rules around arsenic, as well as, lead and copper are currently being re-evaluated.

There are also a number of "emerging" contaminants that are not currently. For example, PFAS (Per- and polyfluoroalkyl substances), for which the EPA has issued a health advisory. PFAS are called "forever chemicals" since they tend not to break down in the environment or the human body and can accumulate over time.

We recommend looking at the contaminants present in Corpus Christi's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.

From Aug. 1, 2014 to Aug. 31, 2014, Corpus Christi had 1 non-health based Safe Drinking Water Act violation with the violation category being Monitoring and Reporting, more specifically, the violation code was Monitoring, Routine Minor (TCR) which falls into the Microbials rule code group, and the Total Coliform Rules rule code family for the following contaminant code: Coliform (TCR).

For the compliance period beginning Sept. 24, 2013, Corpus Christi had 1 non-health based Safe Drinking Water Act violation with the violation category being Other Violation, more specifically, the violation code was Public Notification Violation for NPDWR Violation which falls into the Other rule code group, and the Public Notice Rule rule code family for the following contaminant code: Public Notice.

From April 1, 2013 to June 30, 2013, Corpus Christi had 1 health-based Safe Drinking Water Act violation with the violation category being Maximum Contaminant Level Violation, more specifically, the violation code was Maximum Contaminant Level Violation, Average which falls into the Disinfectants and Disinfection Byproducts Rule rule code group, and the Stage 2 Disinfectants and Disinfection Byproducts Rule rule code family for the following contaminant code: TTHM.

From Jan. 1, 2013 to March 31, 2013, Corpus Christi had 1 health-based Safe Drinking Water Act violation with the violation category being Maximum Contaminant Level Violation, more specifically, the violation code was Maximum Contaminant Level Violation, Average which falls into the Disinfectants and Disinfection Byproducts Rule rule code group, and the Stage 2 Disinfectants and Disinfection Byproducts Rule rule code family for the following contaminant code: TTHM.

Is there Lead in Corpus Christi Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Corpus Christi water system, City of Corpus Christi, between sample start date and sample end date, were at or below, 0.0024 mg/L of lead in Corpus Christi water. This is 16.0% of the 0.015 mg/L action level. This means 10% of the samples taken from Corpus Christi contained more lead.

While Corpus Christi water testing may have found 0.0024 mg/L of lead in its water, that does not mean your water source has the same amount. The amount of lead in water in a city can vary greatly from neighborhood to neighborhood, or even building to building. Many buildings, particularly older ones, have lead pipes or service lines which can be a source of contamination. To find out if your home has lead, we recommend getting you water tested.

No amount of lead in water is healthy, only less dangerous. As lead accumulates in our bodies over time, even exposure to relatively small amounts can have negative health effects. For more information, please check out our Lead FAQ page.

Are there PFAS in Corpus Christi Tap Water?

Currently, testing tap water for PFAS isn’t mandated on a national level. We do have a list of military bases where there have been suspected or confirmed leaks. There appears to be at least one military base - Corpus Christi Texas Naval Air Station - near Corpus Christi with suspected leaks.

With many potential sources of PFAS in tap water across the US, the best information we currently have about which cities have PFAS in their water is this ewg map, which you can check to see if Corpus Christi has been evaluated for yet.

Our stance is better safe than sorry, and that it makes sense to try to purify the tap water just in case.

What do these Violations Mean?

Safe Drinking Water Act Violations categories split into two groups, health based, and non-health based. Generally, health based violations are more serious, though non-health based violations can also be cause for concern.

Health Based Violations

  1. Maximum contaminant levels (MCLs) - maximum allowed contaminant level was exceeded.
  2. Maximum residual disinfectant levels (MRDLs) - maximum allowed disinfectant level was exceeded.
  3. Other violations (Other) - the exact required process to reduce the amounts of contaminants in drinking water was not followed.

Non-Health Based Violations

  1. Monitoring and reporting violations (MR, MON) - failure to conduct the required regular monitoring of drinking water quality, and/or to submit monitoring results on time.
  2. Public notice violations (Other) - failure to immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health.
  3. Other violations (Other) - miscellaneous violations, such as failure to issue annual consumer confidence reports or maintain required records.

PUBLIC PARTICIPATION

Corpus Christi’s Mayor and City Council meet the second, third, and fourth Tuesday of each month. Information about public participation, public comment, and input can be found by visiting www.cctexas.com/departments/ mayor-and-city-council.

UNDERSTAND YOUR WATER SOURCES

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material. Water can pick up substances resulting from the presence of animals or from human and/or industrial activity. Contaminants that may be present in a water source before treatment include microbial, inorganic, pesticide and herbicide, radioactive, and organic chemical contaminants.

Corpus Christi’s water is obtained from a combination of water sources. The Atascosa River and the Nueces River supply water to Lake Corpus Christi, and the Frio River supplies water to Choke Canyon Reservoir. These sources

  • ow down the Nueces River where they are then treated at the O. N. Stevens Water Treatment Plant. Water from the Lower Colorado River is transported through the Mary Rhodes Phase II Pipeline where it meets Lake Texana. Water from Lake Texana is then added and transported through the Mary Rhodes Phase I Pipeline to make the 101-mile journey to the O.N. Stevens Water Treatment Plant.

A Source Water Susceptibility Assessment of our drinking water is available on the Texas Drinking Water Watch website. To view, please visit dww2.tceq.texas.gov/DWW/. The report shows the susceptibility and types of constituents that may come in contact with our water supply source based on human activities and natural conditions.

IMPORTANT HEALTH INFORMATION

Cryptosporidium is a parasite that may be found in untreated surface water. Treatment facilities are required to meet removal standards during the treatment process to ensure drinking water is safe for consumption. Although fi ltration removes Cryptosporidium, it cannot guarantee 100 percent removal. Our previous monitoring indicated the presence of these organisms in our source water in one out of twenty- four samples. Ingestion of Cryptosporidium may cause cryptosporidiosis, an abdominal infection with symptoms such as nausea, diarrhea, and abdominal cramps. Most healthy individuals can overcome the infection within a few weeks.

You may be more vulnerable than the general population to certain microbial contaminants, such as Cryptosporidium, in drinking water. Infants, some elderly, or immunocompromised persons such as those undergoing chemotherapy for cancer; those who have undergone organ transplants; those who are undergoing treatment with steroids; and people with HIV/AIDS or other immune system disorders can be particularly at risk from infections. You should seek advice about drinking water from your physician or health care provider. Additional guidelines on appropriate means to lessen the risk of infection by Cryptosporidium are available from the Safe Drinking Water Hotline at 800-426-4791.

ALL DRINKING WATER MAY

CONTAIN CONTAMINANTS

Treatment of water is regulated by the EPA to ensure it is safe to drink. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk. Contaminants may be found in drinking water that may cause taste, color, or odor problems. These types of problems are not necessarily causes for health concerns. For more information on taste, odor, or color of drinking water, please contact Corpus Christi’s Water Quality Hotline at 361-826-1234. More information about contaminants and potential health effects can also be obtained by calling the EPA’s Safe Drinking Water Hotline at 800-426-4791.

DEFINITIONS OF THE DRINKING WATER QUALITY REPORT TABLE

Action Level (AL) – The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow

Level 1 Assessment – A study of the water system to identify potential problems and determine (if possible) why total coliform bacteria were found

Level 2 Assessment – A very detailed study of the water system to identify potential problems and determine (if possible) why an Escherichia coli (E. coli) maximum contaminant level (MCL) violation occurred and/or why total coliform bacteria were found on multiple occasions

Maximum Contaminant Level (MCL) – The highest level of a contaminant that is allowed in drinking water; MCLs are set as close to the MCLG as feasible using the best available treatment technology

Maximum Contaminant Level Goal (MCLG) – The level of a contaminant in drinking water below which there is no known or expected risk to health; MCLGs allow for a margin of safety

Maximum Residual Disinfectant Level (MRDL) – The highest level of a disinfectant allowed in drinking water; there is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants

Maximum Residual Disinfectant Level Goal (MRDLG) – The level of a drinking water disinfectant below which there is no known or expected risk to health; MRDLGs do not refl ect the benefi ts of the use of disinfectants to control microbial contaminants

Minimum Reporting Level (MRL) – The lowest value that can be reported for a constituent

Parts Per Million (ppm) – Equivalent to milligrams per liter (mg/L)

Picocuries Per Liter (pCi/L) – A measure of radioactivity

HOME PLUMBING PIPES MAY IMPACT YOUR EXPOSURE TO LEAD

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Corpus Christi Water Utilities is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by fl ushing your tap for thirty seconds to two minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at 800-426-4791 or www.epa.gov/safewater/lead.

Secondary Maximum Contaminant Level (SMCL) Non-enforceable guidelines regarding contaminants that may cause aesthetic effects in drinking water but do not pose a health risk

TreatmentTechnique(TT) – A required process intended to reduce the level of a contaminant in drinking water

Turbidity – A measure of clarity of drinking water

Total Organic Carbon (TOC) has no health effects. The disinfectant can combine with TOC to form disinfection byproducts. Disinfection is necessary to ensure that water does not have unacceptable levels of pathogens. Byproducts of disinfection include trihalomethanes (THM) and haloacetic acids (HAA5) which are reported elsewhere in this report. *Removal ratio is the percent of TOC removed by the treatment process divided by the percent of TOC required by TCEQ to be removed.

Cryptosporidium is of great concern in public water systems that treat surface water for drinking water sources. Resistant to disinfectants, Cryptosporidium can cause gastrointestinal illness in individuals who consume contaminated water. The Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) is required by Congress in order to increase protection from microbial contaminants such as Cryptosporidium. Under this rule, water systems must conduct monthly source water Cryptosporidium sampling over a two year span. The city of Corpus Christi completed sampling in July of 2019.

Fecal Coliform bacteria, in particular, E. coli, are members of the coliform bacteria group originating in the intestinal tract of warm-blooded animals and are passed into the environment through feces. The presence of fecal coliform bacteria (E. coli) in drinking water may indicate recent contamination of the drinking water with fecal material. Microbes in these wastes can cause short-term effects, such as diarrhea, cramps, nausea, headaches, and other symptoms. They may pose a special health risk for infants, young children, elderly, and people with severely compromised immune systems.

***A routine sample and a repeat sample are total coliform positive, and one is also fecal coliform or E. coli positive.

WATER LOSS

In the water audit report submitted to the Texas Water Development Board for the time period of January 1, 2020 to December 31, 2020, we produced 23,656,359,202 gallons of treated water. We reported an estimated water loss of 1,861,964,951 gallons or 8.17%. This refers to the amount of water lost due to leaks, water line breaks, or other non- revenue water use.

WATER CONSERVATION

Since the City fi rst started supplying its residents with water in the 1890s, the region has experienced several periods of drought. Over the years, supplies have been added and conservation measures have been strengthened to ensure water security for the residents and businesses of the region. However, with the variability of weather patterns in South Texas and a continually growing population, it is critical that the City plans for future drought conditions. We encourage residents to continue to conserve water as we aspire to provide the highest water quality in Texas.

A little bit goes a long way. Visit our website to learn more about water conservation including xeriscape, drought contingencies, and water efficiency by visiting www.cctexas.com/ conservation.

Sources and Resources

Corpus Christi Tap Water

Corpus Christi is considering the largest city in Texas and is a large Catholic community. The water that runs through the city is considered to be very pure and safe, thanks to the pumping stations that are located throughout the city and the control of the water that is distributed. In order to enjoy the purest tap water possible, you need to know where to find it, and there are many different reasons that one would want to get this water. While the water has benefits of its own, there are also some things that you should know about this water in order to ensure that you are using it safely and getting the best results.

The water that comes from these stations has been studied by the EPA and it has been found that it has very few contaminants. This makes it ideal for drinking, cooking, bathing, and other normal activities that people might do around the water. However, if you are looking for a purifying system, then you will know that the tap water cannot be trusted and you need to find a company that can help you with this.

So what type of steps can you take? Well, first of all, you should know that you can get a reverse osmosis system in order to remove any trace of toxins that may be present in the water. However, these systems can be quite costly, and they do not remove any harmful substances that may be present. If you cannot afford to spend a lot of money on a reverse osmosis system, then you will want to look into other options.

Corpus Christi Drinking Water

Corpus Christi is a city in the Virgin Islands, which is located in the North Carolina Caribbean Sea. In the past, this area was known for its pearl cultivation, but over time, the city has seen a steady decline in tourism due to flooding from Tropical storms and other weather-related events. In addition to the flooding, the soil conditions were poor enough that over four feet of land were lost, and many towns along the coast have since struggled to recover. So, why would anyone want to drink water from Corpus Christi?

The quality of the water supply for Corpus Christi has been a controversial issue since the storm, with some claiming that the water is as bad as, if not worse than, any other major city on the Eastern seaboard. This debate came to a head when officials took water samples and compared them to samples taken from other cities. While no clear winner was found, residents of Corpus Christi expressed doubts about the quality of the water and made complaints to local and state officials. In response to the complaints, the Texas Department of State Health Services issued what is known as an emergency order, which temporarily shut down all water services. Though the effects of the order still aren’t felt, many believe the move was a knee-jerk reaction to the negative public sentiment towards the water supply.

Although the debate surrounding the water quality in Corpus Christi drinking water will continue, it is unlikely that the controversy will impact tourism. While a large segment of the community may feel negatively towards the drinking water, there is also a segment of the population that would prefer to patronize the clean and safe water provided by the city’s water source. Regardless of the debate surrounding the water, the fact remains that the water is a safe alternative to bottled water in the area, and millions of visitors every year are able to find their way around the area without having to worry about where their next water choice will come from.

Corpus Christi’s Water

Corpus Christi’s Water is a Corpus Christi symbol used for cleansing and blessing the waters surrounding the Holy Sepulcher in the Catholic Church. The water that flows out of the Sepulcher, known as the “vas,” is considered to be one of the seven Biblical miracles. Many Christians believe that the water from the Sepulcher can save them from hell and God. They believe that drinking from the water alone will make them feel enlightened and cleansed. In fact, many believe that simply drinking the water itself will cleanse and purify the soul.

People from all denominations, religions, and backgrounds will gather at the church, known as the Church of the Immaculate Conception, on this day of the Water of Pure Water. While the celebration may seem to be one of the many feasts that occur during the month of Lent, it is actually a special day of prayer and meditation for those who attend the church. People often carry prayers or incense in their hands as they walk to the church.

Corpus Christi’s Water is considered a holy gift from the Holy Spirit. The water itself is not alcoholic but it is considered to be the purest type of water available anywhere. The symbolism of Jesus coming down from the Cross and walking into the sepulcher with pure water is considered highly symbolic and is one of the most well-known events on this day. The symbolism of cleansing and being cleansed by water is highly applicable to the Catholic Church.

Corpus Christi Water Utility

The Corpus Christi Water Utility Company in Texas is one of the largest water providers in the State, serving the entire city of Corpus Christi. They are also responsible for providing water to much of South Texas as well as to New Mexico. They have a transmission line that brings water from the City of Corpus Christi to all of the other areas of Texas as well as to New Mexico. They also have over twenty-two thousand miles of water lines laid in the city. This translates to water that runs thirty-six miles between refills.

There are about two thousand four hundred individual homes and businesses that are serviced by the Corpus Christi Water Utility. This translates to about thirteen and a half million people that have access to the water that the utility provides through their pipes. The largest portion of the city is in the downtown area where the downtown parking lots and streets are located. This means that the water pipes are placed on the street or parking lot so that they do not have to be placed in the middle of the city.

Because of how large the city is, it means that there is a lot of water pressure being delivered to homes. Homes in the downtown area use the main sewer line that is located in Conroe, Texas, which means that the pressure that is delivered to them is much higher than homes further away in the city. This gives an advantage to those living downtown. Other residents of Corpus Christi can purchase bottled water or use the alternative method of using filtered water from the company’s filters. This is done through a filter that they sell to consumers.

Corpus Christi Water Quality

Corpus Christi is a beautiful beach town in the northern part of the nation of Texas and although it is not as populated as Galveston or Waco, this quiet little city offers plenty to do, both on land and in the water. This beautiful beach town is known for its wide array of activities including parasailing, boating, swimming, fishing, and water skiing, among many others. The Corpus Christi Water Quality Commission testifies that over 99% of the water contained in the city’s supply meets or exceeds EPA standards.

You might think that a small community would have poor water quality, but the fact of the matter is, Corpus Christi is one of the most environmentally sound cities in all of Texas. For example, the city uses a special filter to help remove small debris, rust, sand, and other particles from its water supply. Also, the water is filtered and treated before it is sent to the public. One reason why Corpus Christi water quality is so good? Because it is one of the few areas in Texas where the wastewater from smaller towns is sent to the Texas General Landfill instead of being discharged into the Gulf of Mexico.

So, what can you do to ensure that your next water process is safe? Make sure to choose an experienced, quality water company to complete all of your needs. There are plenty of companies in and around the Corpus Christi area, and you are sure to find one that suits your needs. Corpus Christi is a naturally beautiful and thriving community. There is no reason why you should not be able to enjoy the sunshine and fun of living in a community that puts your well-being first.

Corpus Christi Water Services

Corpus Christi, a small town just south of San Antonio is well known for having some of the best spring water in Texas. However, there is a major problem with many of the tap water systems in this area. They often use chlorination and fluoride to treat the water, both of which are toxic to fish and the environment.

This is why more than 20 states have banned the use of these harmful chemicals in their water services. Corpus Christi has used these practices for as long as I can remember, but until recently, they were still doing it. The reason they continue to do this is that they know that if everyone stopped using these methods, they would be out of business. In fact, many cities and towns in Texas no longer use chlorination and fluoride treatments to treat the water in their distribution systems because of this.

If you have had bad experiences with your city water services in the past, it may be time to call a plumber for help. The cost of getting chlorinated or dechlorinated from Corpus Christi water services is far too high, even for large homes like mine. I don’t think I should have to explain to anyone why I am putting my health and the health of my family first when dealing with the water we use every day. I also hope that if enough people take notice of what I am saying, that some of these companies will start to see what they are doing to the natural resources of this great state.

Corpus Christi Water Contaminants

Corpus Christi, Texas, is a city located on the Gulf of Mexico, which has a long-standing history as a major port. Corpus Christi is a port and a commercial harbor with facilities to support the shipping and petroleum industries, including refineries and petroleum storage tanks. The city of Corpus Christi is in the San Antonio area of Texas.

The cause of Corpus Christi’s growth as a port and commercial harbor is the Corpus Christi River, which provides water for agriculture and industry. Because the river runoff is so good, it doesn’t enter the inland aquifers as much as other parts of the state, thus lessening pollution in the rivers that feed the Texas rivers. The bay where the Corpus Christi flows has historically had many occurrences of water pollution, with garbage and other solid waste carrying harmful chemicals into the water.

In order to reduce the threat of water contamination, the city and county of Corpus Christi have made some major changes. The biggest one was the building of a desalination plant where seawater can be cleaned and then sent into homes. Another option being used now is chlorination, where chlorine is introduced to kill any remaining bacteria. While both of these methods are effective, they do not remove all of the contaminants.

Corpus Christi Commission on Environmental Quality

The Corpus Christi Commission on Environmental Quality is a government-appointed commission made to examine the effects of the environmental quality of Corpus Christi, a Southern coastal city in the Republic of Texas. It was set up by the State Legislature to make sure that the Corpus Christi beaches were safe from harmful discharges of agricultural chemicals. These agricultural chemicals are used by growers to protect their crops from insects and to make the plants grow faster and stronger. In fact, farmers and industries have contributed largely to the pollution of the city’s groundwater. The commission found that more than two thousand industrial waste chemical bottles containing lead, zinc, cadmium, chromium, and other heavy metals have spilled into the shallow coastal waters around the city.

The commission found that the major sources of pollution in the city’s water supply are from agricultural fields, manufacturing facilities, and wastewater outlets that come from nearby towns and cities. It would seem that whatever business produces the chemicals needed to protect the city’s water is polluting its water. In addition to having contaminated the water, the emissions from power plants and industry contribute to the air pollution of Corpus Christi. A study by the US Environmental Protection Agency estimates that emissions of four hundred tons per year cause ninety-three thousand premature deaths due to the environmental quality of water.

The Corpus Christi Commission on Environmental Quality found that despite the contamination of its groundwater, it did not present a danger to the general public’s health or welfare. Nevertheless, it was required by law to perform an environmental impact assessment that would cost businesses six million dollars, and the local governing authority had asked the commission to carry out this assessment, without public input. For this reason, many residents are dissatisfied with the way the commission has conducted its investigation. Most commission members have failed to properly investigate industry pollution and only focused on the compliance costs that companies have incurred. Even with this commission, the success of reducing pollution to acceptable levels would still depend largely on the public.
